• a. Packaging: 1.0 m x 20 m/roll
• b. Thickness: 1.5mm

a. Substrate preparation:

• The concrete surface must be clean, solid, and free from dirt and sharp objects.
• Any adhesion reduction factors such as oil, loose materials, bitumen, grease, plaster, etc. must be removed.
• Concrete substrate must be dry. Standing water must be cleaned prior to the application of bitumen primer.
• Places with edges or corners, wall footing must be beveled or rounded with mortar or concrete.
• All defects on the concrete surface must be treated with specialized mortar.
• Concrete surface shall not have cracks or gaps ≥ 10 mm. Structural cracks must be repaired before applying waterproofing membranes.

b. Application method:

• LM9001 waterproofing membrane is applied with various bitumen primer types
• Stir the bitumen primer well by low speed mixer for 2 – 3 minutes until a homogeneous mixture
• Make sure concrete surface is dry before the application of bitumen primer.
• Use roller or brush to apply bitumen primer on concrete surface. Consumption shall be based on the primer and surface condition of concrete, the popular quantity is around 0.2 ~ 0.4 kg/m2
• Apply LM9001 membrane within 48 hours after the application of bitumen primer. In case the 48-hour limit is exceeded, bitumen primer layer must be applied again.
• In the case of raining within 6 hours after the completion of bitumen primer layer, the application of bitumen primer must be done again.
• Remove the protecting film layer of LM9001 and place the membrane on the surface of bitumen primer material when it has become non-sticky to the touch.
• Use steel roller to adhere LM9001 to the concrete surface – by rolling the whole membrane firmly.
• LM9001 membranes are joined together by overlapping joints, overlapping width is at least 80mm. Use roller to firmly seal the membranes together.
• The finishing layer should be done on top of the membranes within 10 – 15 days after the application of waterproofing layer. The delay can later affect the duration of the membranes.
